Sysname
(2E,6E)-farnesyl-diphosphate diphosphate-lyase (valerianol-forming)
Reaction(IUBMB)
(2E,6E)-farnesyl diphosphate + H2O = valerianol + diphosphate [RN:
R12456 ]
Reaction(KEGG)
Substrate
Product
Comment
The enzyme was characterized from the trees Camellia hiemalis and Camellia sinensis (black tea). The enzyme from Camellia hiemalis produces (2Z,6E)-hedycaryol as a minor product.
